Kim Jong Un's half-brother soiled underwear during poisoning

North Korean leader Kim Jong Un’s half-brother soiled himself after being assassinated with an odorless poison, according to a doctor.

Kim Jong Nam, who is estranged from his family and has lived abroad for years, was rushed the hospital earlier this year from the airport in Kuala Lumpur, Malaysia, and died hours later.

His home country suggested he died of a heart attack, though surveillance footage showed two young women applying a rag to his face before he begins feeling the effects of what scientists say was the nerve agent VX.

Siti Aisyah of Indonesia and Doan Thi Huong of Vietnam said that they thought they were participating in a prank television show, though are now on trial for Kim’s murder.

Doctor Nurliza Abdullah repeated testimony from earlier in the trial when he said that VX was believed to be the cause of death after traces of it were found on the victim’s face.

Traces of the odorless, tasteless substance, labeled a weapon of mass destruction by the UN, were also found on Aisyah.

He added Monday that the fact that Kim’s pupils contracted and the amount of feces in his underwear also pointed towards poisoning.

Aisyah and Huong face the death penalty if convicted, but are not the only suspects on trial in what local authorities called an assassination by North Korea.

Four people from the isolated kingdom are also suspected in playing a part in the killing, though fled Malaysia shortly after the attack.
